Sierra Vista Exterminators was very quick to respond when I called for service. I hate spiders and saw a black widow. Dale came out right away and sprayed, within minutes I was seeing dead spiders in places I did see them in. I was only going to have them spray the one time, but signed up for service so that I don't have to worry about bugs anymore. They are very nice people, the lady in the office is always polite and answers your questions.
